Abstract
Permasalahan yang diamati dalam penelitian adalah pengaruh panas terhadap
aliran konveksi bebas viskoselastik yang melalui bola berpori dengan penyelesaian
secara numerik menggunakan metode beda hingga skema pusat. Pada aliran konveksi
bebas dapat diuraikan persamaan kontinuitas, momentum, dan energi. Selanjutnya
persamaan pembangun (governing equation) berdimensi yang terbentuk
ditranformasi ke dalam persamaan non-dimensi dan ditranformasi lagi ke dalam
bentuk persamaan non-similar. Berdasarkan hasil simulasi didapat pengaruh
parameter viskoselastik ( ), bilangan Prandtl ( ) dan porositas ( ) terhadap
kecepatan aliran berbanding terbalik, sedangkan pengaruh parameter pembangkit
panas atau heat generation ( ) berbanding lurus. Adapun pengaruh parameter
viskoselastik ( ) dan heat generation ( ) terhapad temperatur fluida berbanding
lurus, sedangkan pengaruh bilangan Prandtl ( ) dan porositas ( ) terhadap
temperatur fluida berbanding terbalik.

Issues raised are free convection flow of viscous-elastic through a porous sphere
with the completion of numerically using central finite difference method. The free
convection flow can described continuity equation, momentum, and energy. Further,
governing equations dimensionless form will be transformed into a non-dimensional
equation and transformed again into a non-similar equations. The results of this
research about the impact of viscoelastic parameter (K), Prandtl number (Pr), and
porosity (P) on the flow velocity profile (f ') is inversely proportional , However
effect of heat generation parameter (γ) on the flow velocity profile (f ') is inversely
proportional. And the effect of the viscoelastic parameters (K) and heat generation
(γ) to the flow temperature profile (θ) is proportional, However the effect of Prandtl
number (Pr) parameter and porosity (P) on the flow temperature profile (θ) is
inversely proportional.
